Comparative Effectiveness of Mechanical Circulatory Support Devices in Cardiogenic Shock

In patients with cardiogenic shock, this review compares the efficacy of percutaneous microaxial left ventricular assist devices (pLVADs) to intra-aortic balloon pumps (IABPs) or no mechanical circulatory support (MCS). End-organ hypoperfusion brought on by insufficient cardiac output characterizes the potentially fatal disease known as cardiogenic shock. Relevant papers were found by a thorough search of internet resources and were incorporated into the study. The main outcomes evaluated were: (1) Short-term mortality, (2) hemodynamic indices, (3) organ function, and (4) Length of hospital stay. Considered secondary outcomes were: (1) Adverse events, (2) quality of life, and (3) long-term survival. As shown by increased cardiac output and mean arterial pressure, the findings of this research imply that pLVADs may provide superior hemodynamic support versus IABPs or no MCS. In addition, pLVADs may have better organ function and lower short-term mortality rates than IABPs or no MCS. However, using pLVADs was also linked to a higher risk of unfavorable outcomes, such as bleeding and vascular issues. Data on long-term survival and quality-of-life outcomes were sparse and ambiguous. In conclusion, as compared to IABPs or no MCS, pLVADs may offer more effective hemodynamic support and better short-term outcomes in patients with cardiogenic shock. More investigation is required to fully comprehend the long-term advantages, hazards, and effects of pLVADs on the quality of life in this patient population.

The clinical course and outcomes of non-aneurysmal subarachnoid hemorrhages in a single-center retrospective study

BackgroundNon-aneurysmal subarachnoid hemorrhages (SAHs) are thought to have a benign clinical course compared to aneurysmal SAHs. The aim of this study is to report the clinical course and outcomes of non-aneurysmal SAHs in a large single-center study.MethodsThe patients with non-aneurysmal SAHs were screened from Tampere University Hospital from 2005 to 2020. The clinical data were collected from the patient’s medical records and from the imaging studies. The primary interest was the neurological outcome assessed by dichotomized GOS at 2 months. Multivariable logistic regression was used to study the factors associated with unfavorable outcome.ResultsWe found 216 non-aneurysmal SAHs in 214 patients (2 patients with > 1 bleed). Ninety-seven percent of patients with a typical perimesencephalic bleeding pattern SAH (PSAH) (75/77) had a favorable outcome, while 86% of patients with non-perimesencephalic SAH (NPSAH) had a favorable outcome (84/98). In a multivariable logistic regression analysis, loss of consciousness (LOC) (aOR 214.67, 95% CI 17.62–2615.89) and Fisher grade 4 bleeding pattern (aOR 23.32, 95% CI 1.40–387.98) were associated with increased risk for unfavorable outcome (GOS 1–3). Vasospasm was seen in 20% of non-aneurysmal SAH patients, hydrocephalus in 17%, and 13% needed ventriculostomy.ConclusionsNon-aneurysmal SAH seems to have a good prognosis for majority of patients, especially for patients with a PSAH. Non-aneurysmal SAH patients are however affected by vasospasm and hydrocephalus and have similar risk factors for poor outcome as patients with aneurysmal SAH. This suggests that it is the severity of the bleed rather than the etiology that associates with poor outcome.

Timing of decongestion and its impact on acute heart failure prognosis.

The risk of unfavourable outcomes after an acute heart failure (AHF) episode remains high. Effective decongestion, reflected by haemoconcentration (HC), may guide therapy. Optimal timing of HC remains unspecified. We analysed the AHF registry to evaluate the prognostic differences of various timing of HC. Subjects were divided into 3 groups by time of reaching HC. The groups differed in terms of 1-year occurrence of a composite of the mortality and AHF hospitalization (26% vs. 46% vs. 40%, early vs. late vs. no HC, p = 0.016). Patients reaching HC earlier seem to present the best prognosis regarding the analysed composite endpoint.

Accurately predicting the risk of unfavorable outcomes after endovascular coil therapy in patients with aneurysmal subarachnoid hemorrhage: an interpretable machine learning model.

Despite endovascular coiling as a valid modality in treatment of aneurysmal subarachnoid hemorrhage (aSAH), there is a risk of poor prognosis. However, the clinical utility of previously proposed early prediction tools remains limited. We aimed to develop a clinically generalizable machine learning (ML) models for accurately predicting unfavorable outcomes in aSAH patients after endovascular coiling. Functional outcomes at 6 months after endovascular coiling were assessed via the modified Rankin Scale (mRS) and unfavorable outcomes were defined as mRS 3-6. Five ML algorithms (logistic regression, random forest, support vector machine, deep neural network, and extreme gradient boosting) were used for model development. The area under precision-recall curve (AUPRC) and receiver operating characteristic curve (AUROC) was used as main indices of model evaluation. SHapley Additive exPlanations (SHAP) method was applied to interpret the best-performing ML model. A total of 371 patients were eventually included into this study, and 85.4% of them had favorable outcomes. Among the five models, the DNN model had a better performance with AUPRC of 0.645 (AUROC of 0.905). Postoperative GCS score, size of aneurysm, and age were the top three powerful predictors. The further analysis of five random cases presented the good interpretability of the DNN model. Interpretable clinical prediction models based on different ML algorithms have been successfully constructed and validated, which would serve as reliable tools in optimizing the treatment decision-making of aSAH. Our DNN model had better performance to predict the unfavorable outcomes at 6 months in aSAH patients compared with Yan's nomogram model.

Elevated Calcium after Acute Ischemic Stroke Predicts Severity and Prognosis.

The aim of this study is to investigate whether there is a correlation between serum calcium levels and clinical severity or functional outcome at discharge in Chinese patients with acute ischemic stroke. Data from 339 patients admitted to our hospital between July 2020 and July 2021 were analyzed. Baseline demographic and clinical information was collected within 24h of admission, including serum calcium levels, stroke severity (measured by the National Institutes of Health Stroke Scale [NIHSS] score), and lesion volumes. The modified Rankin Scale [mRS] assessed functional outcomes at discharge. Our analysis showed that the median age of patients included in the study was 65 years (interquartile range [IQR], 60-70), and 60.8% were men. We found a positive correlation between serum calcium levels and stroke severity (r[spearman] = 0.266, P < 0.001), with calcium levels increasing as stroke severity increased. In a subgroup of 188 patients with available MRI data, serum calcium concentrations positively correlated with infarct size. Furthermore, in multivariate analysis, a calcium serum level in the highest quartile was associated with a higher risk of unfavorable outcome (odds ratios [OR] = 3.27; 95% confidence intervals [CI] = 1.91-5.59; P < 0.001). In conclusion, our study indicates that higher calcium serum levels are associated with stroke severity and early neurologic outcome after acute ischemic stroke, indicating that calcium may serve as a prognostic biomarker for stroke in Chinese patients.

New Perianal Sepsis Risk Score Predicts Outcome of Elderly Patients with Perianal Abscesses.

Antibiotic therapy following surgical perianal abscess drainage is debated, but may be necessary for high-risk patients. Frailty has been shown to increase the risk of unfavorable outcomes in elderly surgical patients. This study aims to identify high-risk patients by retrospectively analyzing a single-center cohort and using a pretherapeutic score to predict the need for postoperative antibiotics and extended nursing care following perianal abscess drainage surgery. The perianal sepsis risk score was developed through univariable and multivariable analysis. Internal validation was assessed using the area under receiver-operating characteristic curve. Elderly, especially frail patients exhibited more severe perianal disease, higher frequency of antibiotic therapy, longer hospitalization, poorer clinical outcomes. Multivariable analysis revealed that scores in the 5-item modified frailty index, severity of local infection, and preoperative laboratory markers of infection independently predicted the need for prolonged hospitalization and anti-infective therapy after abscess drainage surgery. These factors were combined into the perianal sepsis risk score, which demonstrated better predictive accuracy for prolonged hospitalization and antibiotic therapy compared with chronological age or frailty status alone. Geriatric assessments are becoming increasingly important in clinical practice. The perianal sepsis risk score identifies high-risk patients before surgery, enabling early initiation of antibiotic therapy and allocation of additional nursing resources.

Clinicopathological Risk Factors of Unfavorable Outcomes in Vietnamese Women with Primary Invasive Breast Cancer: A Retrospective Cohort Study.

The rate of unfavorable outcomes, such as recurrence and death, in women with invasive breast cancer varies widely across countries and populations. Identifying those with high-risk profiles is critical so that early detection, prediction, and intervention can be made to improve their survival rate. Therefore, our study evaluated the rate of unfavorable outcomes and its association with clinicopathological characteristics in Vietnamese women with primary invasive breast cancer. A retrospective open cohort study was conducted on Vietnamese women with invasive breast cancer who underwent a mastectomy and were regularly followed up by the hospitals. Kaplan-Meier method was used to estimate the rate of unfavorable outcomes to take into account the follow-up time of each patient. Univariate and multiple Cox regression analyses were conducted to examine the associations between unfavorable outcomes and clinicopathological characteristics. Among 204 women included in the data analysis, the mean age was 54.4 ± 10.9 years. The majority of patients were diagnosed with early-stage (76.5%) or locally advanced (22.5%) breast cancer. The 5-year rate of unfavorable outcomes was 12.8%, and the 8-year rate was 31.7%. Patients with advanced stages had a higher risk of unfavorable outcomes compared to those with early stages (IA, IIA, T2N1). Patients with lymph node metastases and those with triple-negative molecular classification had significantly higher rates of unfavorable outcomes. Although Vietnamese women with breast cancer have a relatively low rate of unfavorable outcomes compared to other countries, findings from this study emphasize the importance of early detection and underscore the need for targeted interventions for patients with advanced stages, lymph node metastases, and triple-negative breast cancer to optimize their treatment, outcomes, and overall prognosis.

Pulmonary Thrombosis despite Therapeutic Anticoagulation in COVID-19 Pneumonia: A Case Report and Literature Review

The rate of thrombotic complications in COVID-19 patients is high and could be associated with the risk of unfavourable outcomes. Moreover, pulmonary thrombotic events can occur even in patients already on anticoagulant treatment. We present the case of a patient with severe COVID-19 pneumonia, without traditional risk factors for thrombosis, who developed massive pulmonary thrombosis (PT) despite therapeutic anticoagulation. The diagnosis was challenging, and the case raised concerns about the protective role of conventional anticoagulant treatment in COVID-19 pneumonia. Thus, we searched for literature reports on COVID-19 patients who developed PT despite being under anticoagulation therapy. We identified 13 cohort studies including 4058 patients of which 346 (8.5%) developed PT and nine case reports/series enrolling 14 patients. Four cohorts were further analysed, which reported data on risk factors for thrombosis, outcomes and biological characteristics. We found that there were no differences between patients with and without PT regarding the classical risk factors for thrombosis. PT occurred regardless of the anticoagulation regimen, and the risk factor identified was severe COVID-19 pneumonia and a stay in an intensive care unit (ICU). Pulmonary thrombotic events in patients with COVID-19 are rather inflammation-related than correlated with traditional thromboembolic risk factors, and the therapeutic approach must take into consideration this aspect.

The significance of SARC-F scores in predicting postoperative outcomes of older adults undergoing elective major surgery for urologic cancer

Recently, the strength, assistance with walking, rise from a chair, climb stairs, and falls (SARC-F) questionnaire has been developed to screen patients with signs of sarcopenia. However, its clinical benefit remains uncertain in elderly patients undergoing elective major surgeries. This study aimed to explore the role of the SARC-F questionnaire as a screening tool for patients who plan to undergo elective major surgery for urologic cancer and to also evaluate correlations of SARC-F scores with established indicators of sarcopenia. This retrospective observational study enrolled 815 patients over 40 years of age undergoing elective major surgery for urologic cancer and who were screened with the SARC-F questionnaire, preoperatively. The primary endpoint was an association between SARC-F scores and postoperative ambulation failure. Here we define postoperative ambulation failure as a condition where a patient is unable to walk independently within 2 days after surgery and required physical rehabilitation or was transferred to other hospitals in a bedridden state. The secondary endpoint was an association between SARC-F scores and overall survival (OS). Psoas muscle density (PMD) and psoas muscle index (PMI) were calculated from abdominal computed tomography images, and their correlations with SARC-F scores grouped by sex. Of the 815 patients, 738 (91%) were male and the median age was 72 years. Although SARC-F scores weakly correlated with PMD in males and moderately correlated in females (ρ=-0.222 and ρ=-0.474, respectively), their correlation with PMI was negligible (ρ=-0.179 and ρ=-0.084, respectively). SARC-F scores successfully discriminate postoperative ambulation failure in both males and females with the respective area under the receiver operating characteristic curve of 0.856 and 0.813. Multivariate analysis also showed that SARC-F scores greater than 4 are an independent risk factor of postoperative ambulation failure along with older age, lower PMD, and poor performance status. SARC-F scores greater than 4 were significantly associated with a shorter OS in the whole cohort (P<0.001) and a subgroup of patients undergoing radical cystectomy (P=0.03; median follow-up of 515 days). The SARC-F questionnaire might be applicable to identify elderly patients at a higher risk of unfavourable outcomes after major urologic cancer surgery. A randomised controlled trial is necessary to confirm this finding.

Development and validation of prediction scores for the outcome associated with persistent inflammation, immunosuppression, and catabolism syndrome among patients with trauma

BackgroundPersistent inflammation, immunosuppression, and catabolism syndrome (PICS) has impacted on long-term prognosis of patients with trauma. We aimed to identify patients with trauma at risk of PICS-related complications early in...

Tixagevimab/Cilgavimab as pre-exposure prophylaxis against SARS-CoV-2 in patients with hematological malignancies.

The approved combination of Tixagevimab/Cilgavimab has been shown to decrease the rate of symptomatic SARS-CoV-2 infection in patients at increased risk of inadequate response to vaccination. However, Tixagevimab/Cilgavimab was tested in a few studies that included patients with hematological malignancies, even if this population has shown an increased risk of unfavorable outcomes following infection (with high rates of hospitalization, intensive care unit admission, and mortality) and poor significant immunization following vaccines. We performed a real-life prospective cohort study to evaluate the rate of SARS-CoV-2 infection following pre-exposure prophylaxis with Tixagevimab/Cilgavimab in anti-spike seronegative patients compared to a cohort of seropositive patients who were observed or received a fourth vaccine dose. We recruited 103 patients with a mean age of 67 years: 35 (34%) received Tixagevimab/Cilgavimab and were followed from March 17, 2022, until November 15, 2022. After a median follow-up of 4.24 months, the 3-month cumulative incidence of infection was 20% versus 12% in the Tixagevimab/Cilgavimab and observation/vaccine groups respectively (HR 1.57; 95% CI: 0.65-3.56; p = 0.34). In this study, we report our experience with Tixagevimab/Cilgavimab and a tailored approach to SARS-CoV-2 infection prevention in patients with hematological malignancies during the SARS-CoV-2 omicron surge.

Prognostic Value of Cystatin C as a Predictor of Adverse Outcome in Severe Pneumonia Associated with COVID-19

Objective. To assess the cystatin C (CysC) prognostic value for probability of death in patients with severe and extremely severe pneumonia associated with COVID-19.Material and methods. A single-center prospective study included 72 patients with severe and extremely severe pneumonia associated with COVID-19 undergoing treatment in the ICU of multifunctional medical center from September 2020 to October 2021. Recovered survivors (N=55) were analyzed as a Group 1, nonsurvivors (N=17) were considered as a Group 2.Results. The serum (s-CysC) and urine (u-CysC) CysC concentrations were significantly lower in Group 1 patients vs Group 2, averaging 1.31 mg/l vs 1.695 mg/l (P=0.013550), and 0.25 mg/l vs 0.94 mg/l (P=0.026308), respectively. Significant differences were also revealed in the subgroups differed by age (P=0.0094), platelet count (P=0.001), serum fibrinogen concentration (P=0.016), as well as CURB (P=0.02334), CRB-65 (P=0.032564), and SOFA (P=0.042042) scores. Therefore, s-CysC and u-CysC were statistically significant predictors of death in patients with pneumonia associated with severe and extremely severe COVID-19: 16.273 (95% CI: 2.503–105,814), P=0.003 and 1.281 (95% CI: 1.011–1.622), P=0.040, respectively. Urine and serum CysC were established as predictors of death in pneumonia associated with severe and extremely severe COVID-19, where u-CysC was defined as highly informative (ROC AUC 0.938 (95% CI: 0.867–1.000; P=0.000), with 90% sensitivity and specificity), and s-CysC — as informative (ROC AUC 0.863 (95%CI: 0.738–0.988; P=0.000) with 80% sensitivity and 72% specificity) predictive markers.Conclusion. Levels of S-CysC and u-CysC are of high prognostic significance and may contribute to identifying patients at a high risk of unfavorable outcome (death) due to pneumonia associated with severe and extremely severe COVID-19. Both S-CysC and u-CysC concentrations increasing up to 1.44 mg/l and 0.86 mg/l, respectively, were associated with high probability of death.

The DAMAGE CONTROL technique applied in a child injured in a traffic accident after intraabdominal bleeding relapse

EDITORIAL COMMENT. This clinical observation presents an effective application of elements of the abdominal damage-control tactics after postoperative intra-abdominal bleeding relapse under developed coagulopathy and previously underestimated liver damage during surgery. If an “unstable” patient with prolonged internal bleeding is admitted, it is recommended to apply this tactics in the primary surgical intervention with liver packing which would prevent postoperative bleeding and further development of coagulopathy. After patient’s hemodynamics is stabilized, it is necessary to make a complete patient’s examination so as to timely detect all associated injuries. Introduction. Closed trauma of abdominal organs in children in some cases is accompanied by severe complications or death. At the same time, liver injury occupies a leading place in the structure of the abovementioned pathology. Currently, in case of severe injuries of the abdominal organs accompanied by unstable hemodynamics and with a high risk of unfavorable outcomes after radical surgical intervention, surgeons prefer to apply the damage control technique in such patients. Material and methods. The authors discuss a case of successful management of a child injured in a traffic accident. He had multiple closed liver injuries of class III and hemorrhagic shock of degree 3. The DAMAGE CONTROL technique was applied during relaparotomy after intra- abdominal bleeding relapse developed. Results. In this given case, the damage control technique has promoted a successful outcome after staged surgical treatment without any complications in the immediate and late postoperative periods. Conclusion. In case of abdominal cavity trauma in children having hemorrhagic shock and prolonged bleeding from liver wounds, the damage control technique promotes stabilization of patient’s state, arrests bleeding and gives precious time to finish surgical intervention in more favorable situation for both patients and surgeons.

Nomogram to predict unfavorable outcome of endovascular thrombectomy for large ischemic core.

The prognosis for patients presenting with a large ischemic core (LIC) following endovascular thrombectomy is relatively poor. This study aimed to construct and validate a nomogram for predicting 3-month unfavorable outcome in patients with anterior circulation occlusion-related LIC who underwent endovascular thrombectomy. A retrospective training cohort and a prospective validation cohort of patients with a large ischemic core were studied. The diffusion weighted imaging related radiomic features and pre-thrombectomy clinical features were collected. After the selection of relevant features, a nomogram predicting modified Rankin Scale score of 3-6 as an unfavorable outcome was established. The discriminatory value of the nomogram was evaluated with a receiver operating characteristic curve. A total of 140 patients (mean age 66.3 ± 13.4 years, 35% female) were included in this study, consisting of a training cohort (n = 95) and a validation cohort (n = 45). The percentage of patients with an mRS scores of 0-2 was 30%, 0-3 was 40.7%, and 32.9% were dead. Age, National Institute of Health Stroke Scale (NIHSS) score, and two radiomic features, Maximum2DDiameterColumn and Maximum2DDiameterSlice, were identified as factors associated with unfavorable outcome in the nomogram. The nomogram demonstrated an area under the curve of 0.892 (95% confidence interval [CI], 0.812-0.947) in the training dataset and 0.872 (95% CI, 0.739-0.953) in the validation dataset. This nomogram, which includes age, NIHSS score, Maximum2DDiameterColumn, and Maximum2DDiameterSlice, may predict the risk of unfavorable outcome in patients with LIC caused by anterior circulation occlusion.

#3242 OUTCOMES OF THERAPEUTIC PLASMA EXCHANGE: A ONE-YEAR EXPERIENCE IN AN INTERNAL MEDICINE INTENSIVE CARE UNIT

Abstract Background and Aims There is uncertainty regarding the best indication, device type, frequency, length of time, kind of replacement fluid, and criteria for ceasing therapeutic plasma exchange (TPE) for various disorders. TPE is an intrusive technique that has the potential to save lives, but it also has a risk of unfavorable outcomes and complications, necessitating close supervision by professional teams. In the intensive care unit (ICU), there are three categories of indications for TPE: (1) absolute, well-established, and evidence-based, for which TPE is recognized as first-line therapy; (2) relative; for which TPE is a recognized second-line treatment (alone or in combination) and (3) rescue therapy; for which TPE is used with a limited or theoretical evidence base. The purpose of this study is to continue our evaluation of the outcome of nephrology care in internal medicine ICU regarding bedside membrane therapeutic plasma exchange. Method In the continuity of our previous work in the analysis of the outcome of TPE. From August 2021 to August 2022, 425 membrane plasma exchange sessions were performed on 69 patients in the internal medicine department's ICU-Cairo University Hospitals-Egypt. Results Closely similar to what we found before; the most frequent diagnosis was thrombotic microangiopathies (24 (34.8%) patients) with complete recovery seen in 18/24 patients (75%); followed by systemic vasculitis with pulmonary renal involvement (14 (20.3%) patients) with partial remission was seen in 9/14 patients (64.3%); Guillain-Barré syndrome (13 (18.8%) patients) with complete recovery was seen in 8/13 patients (61.5%); Proliferative Lupus Nephritis with crescents [10 (14.5%) patients] with partial remission in 8/10 patients (80%), and myasthenia gravis [8 (11.6%) patients] with complete recovery in 6/8 patients (75%). Hypotension occurred during 69/425 (16.2%) sessions and hypocalcemia in 8/69 (11.5%) patients during treatment. Infection of vascular access occurred in 4/69 (5.8%) patients. 6/69 (8.7%) patients died during their stay in ICU none during treatment with TPE, all of them were diagnosed to have severe sepsis as a cause of death. Conclusion According to our experience, membrane therapeutic plasma exchange is a successful and secure treatment for a variety of illnesses including thrombotic microangiopathies, systemic vasculitis, myasthenia gravis, proliferative lupus nephritis, and Guillain-Barré syndrome. The main reason for death was sepsis.

Epigenetic and Metabolomic Biomarkers for Biological Age: A Comparative Analysis of Mortality and Frailty Risk.

Biological age captures a person's age-related risk of unfavorable outcomes using biophysiological information. Multivariate biological age measures include frailty scores and molecular biomarkers. These measures are often studied in isolation, but here we present a large-scale study comparing them. In 2 prospective cohorts (n = 3 222), we compared epigenetic (DNAm Horvath, DNAm Hannum, DNAm Lin, DNAm epiTOC, DNAm PhenoAge, DNAm DunedinPoAm, DNAm GrimAge, and DNAm Zhang) and metabolomic-based (MetaboAge and MetaboHealth) biomarkers in reflection of biological age, as represented by 5 frailty measures and overall mortality. Biomarkers trained on outcomes with biophysiological and/or mortality information outperformed age-trained biomarkers in frailty reflection and mortality prediction. DNAm GrimAge and MetaboHealth, trained on mortality, showed the strongest association with these outcomes. The associations of DNAm GrimAge and MetaboHealth with frailty and mortality were independent of each other and of the frailty score mimicking clinical geriatric assessment. Epigenetic, metabolomic, and clinical biological age markers seem to capture different aspects of aging. These findings suggest that mortality-trained molecular markers may provide novel phenotype reflecting biological age and strengthen current clinical geriatric health and well-being assessment.

Lateral Humeral Condyle Fractures in Pediatric Patients.

Lateral humeral condyle fractures are frequently seen in pediatric patients and have a high risk of unfavorable outcomes. A fall on the outstretched arm with supination of the forearm is the most common trauma mechanism. A physical examination combined with additional imaging will confirm the diagnosis. Several classifications have been described to categorize these fractures based on location and comminution. Treatment options depend on the severity of the fracture and consist of immobilization in a cast, closed reduction with percutaneous fixation, and open reduction with fixation. These fractures can lead to notable complications such as lateral condyle overgrowth, surgical site infection, pin tract infections, stiffness resulting in decreased range of motion, cubitus valgus deformities, 'fishtail' deformities, malunion, non-union, avascular necrosis, and premature epiphyseal fusion. Adequate follow-up is therefore warranted.

PRESCRIPTIVE APPROPRIATENESS OF CHOLESTEROL-LOWERING DRUGS AMONG PATIENTS ATTENDING CARDIAC REHABILITATION AFTER ATHEROSCLEROTIC CARDIOVASCULAR DISEASE. RETROSPECTIVE STUDY

Objective: Cardiovascular (CV) diseases still represent one on the main causes of death. The promotion of a healthy lifestyle and active treatment of CV risk factors such as cholesterol level is mandatory to reduce risk of unfavourable outcome. Aim of the present study was to investigate the prescriptive appropriateness of cholesterol-lowering drugs among patients who experienced an atherosclerotic CV disease (ASCVD). Design and method: We investigate 155 patients who experienced an ASCVD and underwent cardiac rehabilitation in 2020. The ESC 2021 guidelines on CVD prevention and 2019 ESC Guidelines on dyslipidaemias were followed to detect appropriateness; SCORE2 and SCORE2-OP risk estimation were used to detect patients’ CV risk profile. For the analysis patients were divided into two groups: 1 (n = 118) patients admitted for the first CV event, 2A (n = 18) patients who experienced a previous CV event and were admitted for a second event, 2B (n = 19) patients within a previous CV event within 2 years. LDL cholesterol (c-LDL) was detected at admission to hospital, during rehabilitation and at the first visit after rehabilitation, within 6 to 12 months. Results: Mean age of study participants was 66 years (41-88), 88.4% were males, 72% were overweight/obese, 25% diabetic, 37% smokers, 60% hypertensives, 57% dyslipidemic. Among group 1 patients, with no previous CV events, only 5.1% had low/moderate risk, 44.1% high risk and 50.8 very high risk according to SCORE2 or SCORE2-OP calculator. Mean c-LDL at admission to hospital was 121.5 mg/dl, 58.8 mg/dl during rehabilitation 58mg/dl at the subsequent medical visit. 32.6% reached c-LDL&lt;55 mg/dl, 96.6% with high intensity statin (as monotherapy or associated to ezetimibe). 67.4% did not reach c-LDL&lt;55mg/dl, despite 93.3% were treated with high intensity statin alone or plus ezetimibe. Among group 2A patients 47.1% reached c-LDL&lt;55 mg/dl by mean of high intensity statin (87.5%), while among 2B patients only 3 subjects reached c-LDL&lt;40 mg/dl. Conclusions: This retrospective study confirmed the importance of primary prevention and the utility to calculate CV risk profile. The main limitations for the efficacy lipid lowering drugs resulted: patient's compliance, drugs side effects, lifestyle habits and collaboration with general practitioner.

Benefit of post-operative radiation therapy for incompletely resected stage I-IIIA non-small cell lung cancer: An analysis of the National Cancer Database.

8558 Background: The presence of micro-residual (R1) or macro-residual (R2) disease in non-small cell lung cancer (NSCLC) is associated with a higher risk of recurrence. The benefits of post-operative radiation therapy (PORT) in incompletely resected NSCLC is not clear. The purpose of this study is to compare median overall survival (mOS) of treatment modalities in the post-operative setting for resected stage I-IIIA NSCLC with residual disease (R1/R2) and to determine if PORT provides benefit in this patient population using the National Cancer Database (NCDB). Methods: From the NCDB dataset for the years of 2006-2016, we extracted patients diagnosed with stage I-IIIA NSCLC and who had incomplete resection with residual disease (R1/R2). Kaplan-Meier analysis was performed to differentiate the effect of different post-operative treatment modalities, concurrent chemo-radiotherapy (CCRT), sequential chemo-radiotherapy (SCRT) and chemotherapy (CT) alone on mOS. Subsequently, univariate Cox regression was used to identify statistically significant variables, then multivariate Cox regression was performed to establish variables that contributed to the survival. Lastly, multinomial logistic regression was utilized to establish association of the independent factors. SAS version 9.4 was used to analyze the data. Results: Among the 2701 patients who met inclusion criteria, the average age was 64.1, 64.8 and 65.9 year old for CCRT, SCRT and CT, respectively. Male's constituted 53.6% and white's were 88.1%, and patient's were distributed equally across clinical stages. The majority of patients received SCRT (51.7%) followed by CT alone (39%), and CCRT (9.2%). There were no statistically significant differences in mOS between the different treatment modalities (p=0.220). Patients with R2 were 177% more likely to receive CCRT than CT compared to R1 (OR 2.77, CI 1.86-4.13 and p&lt;0.001). Male's were 28% more likely to receive SCRT than CT compared to females (OR 1.28, CI 1.08-1.52 and p=0.0041). Nodal involvement was associated with decreased mOS with N2/N3 having 37% lower mOS compared to N0 (HR=1.37, CI 1.19-1.57 and p&lt;0.0001). Patients who had R2 disease had a 38% lower mOS compared to those R1 (HR 1.38%, CI 1.19-1.62, p&lt;0.0001). Conclusions: Despite the risk of unfavorable outcomes for patients with residual disease after surgery for NSCLC, the addition of radiotherapy, either concurrently or sequentially, to CT did not offer statistically significant mOS benefit compared to CT alone. Given the known toxicities of radiation, and the lack of impact on survival, the benefit of post-operative radiation is questionable among patients with residual disease after resection.

COVID-19 Vaccination and Clinical Outcomes at a Secondary Referral Hospital During the Delta Variant-dominant Period in West Sumatra, Indonesia.

The second wave of coronavirus disease 2019 (COVID-19) cases in Indonesia, during which the Delta variant predominated, took place after a vaccination program had been initiated in the country. This study was conducted to assess the impact of COVID-19 vaccination on unfavorable clinical outcomes including hospitalization, severe COVID-19, intensive care unit (ICU) admission, and death using a real-world model. This single-center retrospective cohort study involved patients with COVID-19 aged ≥18 years who presented to the COVID-19 emergency room at a secondary referral teaching hospital between June 1, 2021 and August 31, 2021. We used a binary logistic regression model to assess the effect of COVID-19 vaccination on unfavorable clinical outcomes, with age, sex, and comorbidities as confounding variables. A total of 716 patients were included, 32.1% of whom were vaccinated. The elderly participants (≥65 years) had the lowest vaccine coverage among age groups. Vaccination had an effectiveness of 50% (95% confidence interval [CI], 25 to 66) for preventing hospitalization, 97% (95% CI, 77 to 99) for preventing severe COVID-19, 95% (95% CI, 56 to 99) for preventing ICU admission, and 90% (95% CI, 22 to 99) for preventing death. Interestingly, patients with type 2 diabetes had a 2-fold to 4-fold elevated risk of unfavorable outcomes. Among adults, COVID-19 vaccination has a moderate preventive impact on hospitalization but a high preventive impact on severe COVID-19, ICU admission, and death. The authors suggest that relevant parties increase COVID-19 vaccination coverage, especially in the elderly population.
